Installation, Maintenance & Safety Information
| Installation Notes | Install only to approved foundation, mast and rigging drawings. Verify structural alignment, boom heel pins, sheaves, winches, brakes, limit devices and wire-rope reeving. Conduct inspection, functional testing and proof-load testing before service. |
|---|---|
| Maintenance Tips | Inspect wire ropes, sheaves, pins, hooks, blocks, brakes and foundations at prescribed intervals. Lubricate bearings and ropes with compatible products, check corrosion and cracking, and renew worn parts within maker or class limits. Maintain the cargo gear register. |
| Safety Notes | Never exceed the marked safe working load or approved operating angles. Use trained personnel, certified loose gear and agreed signals. Keep personnel clear of suspended loads and snap-back zones, account for vessel motion, and stop operation if brakes, ropes or structures show defects. |
